How to Prepare for NDA: 15 Days NDA Preparation Tips

Here are a few NDA Preparation Tips tips that will help you utilize the above table efficiently.

  • In the first three days, you must get yourself to a good start. In the Mathematics section, start practicing with algebra, matrices & determinants and vector algebra to build a strong foundation. Hovering around moderate difficulty, there are easily around 30-35 questions from this section on the NDA exam. On the GAT, it is crucial to begin your NDA Preparation online or offline in English with a base of English Grammar. Practice one or two Reading comprehension questions, make a list of 15-20 words of vocabulary and read topic related articles.
  • In the next three days, tackle Analytical Geometry Of 2 and 3 Dimensions and Differential Calculus in Mathematics and Chemistry & General Science in GAT. Attempt short topic-based questions at the end. You can also refer to trusted refresher or revision for material NDA Preparation online.
  • On days 7-9, limit yourself to integral calculus which is going to take up time. On the GAT, cover important topics like freedom movement and the Indian Constitution to cement your understanding of Indian History. Cover important revolutions and UN organizations as well. Around 20 questions, going by the trend, are asked from the calculus section.
  • On days 10-12, prepare Trigonometry, Statistics & Probability and Geography. While statistics may take a lot of time, it is instrumental to go through fundamental topics thoroughly.
  • The table mentions quite a few tests and that is because it is a great way of learning in later stages. To get you a grip over current events, the table advises taking 1 short current events every three days. During the last three days attempt complete and timed mock tests. You can take NDA Preparation online tests as well.

One of the most successful NDA Preparation tips is to have faith in yourself and remain confident. Trust your ability and keep feelings of nervousness and expectations at bay. All the best.
